Invalid hostname?

I’ve added 2 different machines so far. One is Windows 7 and the other is Windows 8.1. Both machines are on the domain, and both can be pinged using either ip or hostname, but fog continues to say “Invalid hostname” on the Host Management Screen, next to each device.

I’m using version 0.33B (downloaded on 1/31).

Any suggestions on where to start troubleshooting?
